00:00How Bald Eagles and Ospreys Returned from the Brink of Extinction
00:04Bald eagles and ospreys are proof that conservation can work.
00:08But their comeback started with a crisis.
00:12In the mid-1900s, pesticides like DDT built up through fish
00:16and moved into the bodies of birds that depended on those fish.
00:21The adults did not always die right away.
00:24The eggs did.
00:26Shells became too thin.
00:29Nests failed.
00:30Chicks never hatched.
00:33For bald eagles, the national symbol was sliding toward disappearance in the lower 48 states.
00:39Ospreys, the fish hawks of coastlines, lakes, and rivers suffered similar reproductive damage.
00:45Then, humans changed course.
00:48DDT was banned in the United States in 1972.
00:52The Endangered Species Act added legal muscle.
00:56Nest protection, habitat cleanup, reintroduction work, hacking programs, monitoring, and artificial osprey platforms help the birds recover.
01:05Today, seeing an eagle over a river or an osprey diving feet first into the water can feel normal again.
01:11That normality is the victory.
01:14But recovery is not the same as invincibility.
01:18Power lines, bleed poisoning, contaminated water, habitat loss, boat traffic, drones, and nest disturbance still create risks.
01:26The lesson is bigger than two birds.
01:30Humans damaged the food chain.
01:32Then humans repaired part of it.
01:35And the sky answered with wings.
01:37Thanks.
01:37Thanks.
01:38Let's go.
01:38Thanks.
